DD here:
That's not always true. If they have 2 illnesses at once they might need the stronger antibiotic, but not always. And if they get sick more than once within a few hours, penicillin might not work. Or maybe they don't need antibotics at all, but that's unlikely. I'll give a quick example: Kristina was sick. I healed her. A few days later (it was unpaused most of the time) she was sick again. I "healed" her, then did a doctor consult. She needed the strongest antibiotic. I found it odd, but I'm glad I caught it early. What I'm saying here is that your theory is not completly true.
BTW, I kept having to fix my mistakes! I'm not good at typing.
